ADA, gnat, rtems 6, ubuntu 22LTS

[Frank Kühndel]

Hello Emanuel,

I cannot say anything about your specific issue. I can just provide this 
information:

Our CI/CD builds rtems-tools with ADA on Ubuntu 22.04 for RSB, Git 
commit 35c73203df1e0bc7f0935cfb37ebc6581d8f1103 for aarch64, arm, bfin, 
i386, m68k, mips, moxie, nios2, or1k, powerpc, riskv, sparc, x86_64. The 
other architectures seem to have problems. Moreover, ADA is only build 
but not tested.

The big issue between building with and without ADA comes down to have 
Ubuntu specially setup for the RTEMS Source Builder to being able to 
build ADA. I need these packages:

bzip2
gcc-12
g++-12
gnat-12

And I need the following links (all g** compiler tools must have the 
same version 12 and all must be available without the "-12" postfix):

ln -s gcc /usr/bin/cc

for exe in /usr/bin/gcc*12 /usr/bin/gcov*12 /usr/bin/g++*12; do
    ln -s $exe ${exe%-12}
done

Greetings
Frank
